Find out more about the asteroid

An asteroid the size of an Olympic swimming pool will whizz past the Earth tonight!

But don't worry experts say the space rock known as '2012 DA 14' won't crash into our planet.

The asteroid will zoom past the Earth at a distance of just 28,000 kilometres - the closest ever predicted for an object of that size.

It won't be travelling slowly either - racing past at a blistering 7.8 kilometres a second.

Experts predict the rock will be at its closest to the planet at 19:25 tonight and if you look up in the night sky you may even see it.
